Leif Tibell
Leif Tibell (born 16 November 1944) is a Swedish lichenologist and Emeritus Professor at the University of Uppsala. He is known for his expertise on calicioid lichens. He was awarded the Acharius Medal in 2012 for lifetime achievements in lichenology. Biography Tibell was born in Gothenburg, Sweden, in 1944. He developed an interest in lichens at a young age after meeting the prominent lichenologist Gunnar Degelius through the Gothenburg Botanical Garden, where they were both members. Degelius mentored Tibell, and recommended to him that he should study the subject at Uppsala University, which he did after moving there in the mid 1960s. He continued with graduate studies under the supervision of Rolf Santesson after accompanying him on a research excursion to Norway's Varanger Peninsula in 1966. Santesson was Curator of the Herbarium at the Botany Department. He was also the father of Johan Santesson, who knew Tibell through an organic chemistry research group they we ...

Lichenology
Lichenology is the branch of mycology that studies the lichens, symbiotic organisms made up of an intimate symbiotic association of a microscopic alga (or a cyanobacterium) with a filamentous fungus. Study of lichens draws knowledge from several disciplines: mycology, phycology, microbiology and botany. Scholars of lichenology are known as lichenologists. History The beginnings Lichens as a group have received less attention in classical treatises on botany than other groups although the relationship between humans and some species has been documented from early times. Several species have appeared in the works of Dioscorides, Pliny the Elder and Theophrastus although the studies are not very deep. During the first centuries of the modern age they were usually put forward as examples of spontaneous generation and their reproductive mechanisms were totally ignored. For centuries naturalists had included lichens in diverse groups until in the early 18th century a French researc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Chaenothecopsis Tibellii
''Chaenothecopsis'' is a genus of about 40 species of pin lichens in the family Mycocaliciaceae. Many of the species are resinicolous, meaning they grow on conifer resin or other plant exudates. Most common host plants are trees in the genera ''Abies'', ''Picea'', and ''Tsuga''. Taxonomy The genus was circumscribed in 1927 by Finnish lichenologist Edvard August Vainio.

Caloplaca Tibellii
''Caloplaca'' is a lichen genus comprising a number of distinct species. Members of the genus are commonly called firedot lichen, jewel lichen.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, gold lichens, "orange lichens", but they are not always orange, as in the case of '' C. albovariegata''. The distribution of this lichen genus is worldwide, extending from Antarctica to the high Arctic. It includes a portion of northern North America and the Russian High Arctic. There are about thirty species of ''Caloplaca'' in the flora of the British Isles. An example species in this genus is '' Caloplaca saxicola'', a lichen with worldwide distribution including the Antarctic continent, Europe and northern North America including the northern reaches of the Canadian boreal forests. A new species of ''Caloplaca'', '' C. obamae'', the first species to be named in honor of Barack Obama, was discovered in 2007 on Santa Rosa Island in California and ...

Atla Tibelliorum
''Atla tibelliorum'' is a rare species of saxicolous (rock-dwelling) in the family Verrucariaceae. Found in Finland and the United States, it was formally described as a new species in 2016 by Juha Pykälä and Leena Myllys. The type specimen was collected by the first author near Toskaljärvi lake (, Enontekiö); there, in a calcareous alpine grassland at an altitude of , the lichen was found growing on dolomite pebbles. It has also been collected from Franklin Bluffs, Alaska, where it was growing on high- pH soil in dwarf shrub tundra. The species epithet ''tibelliorum'' honours "Sanja and Leif Tibell Leif Tibell (born 16 November 1944) is a Swedish lichenologist and Emeritus Professor at the University of Uppsala.

Taxon
In biology, a taxon ( back-formation from '' taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Festschrift
In academia, a ''Festschrift'' (; plural, ''Festschriften'' ) is a book honoring a respected person, especially an academic, and presented during their lifetime. It generally takes the form of an edited volume, containing contributions from the honoree's colleagues, former pupils, and friends. ''Festschriften'' are often titled something like ''Essays in Honour of...'' or ''Essays Presented to... .'' Terminology The term, borrowed from German, and literally meaning 'celebration writing' (cognate with ''feast-script''), might be translated as "celebration publication" or "celebratory (piece of) writing". An alternative Latin term is (literally: 'book of friends'). A comparable book presented posthumously is sometimes called a (, 'memorial publication'), but this term is much rarer in English. A ''Festschrift'' compiled and published by electronic means on the internet is called a (pronounced either or ), a term coined by the editors of the late Boris Marshak's , ''Eran ud A ...

Monograph
A monograph is a specialist work of writing (in contrast to reference works) or exhibition on a single subject or an aspect of a subject, often by a single author or artist, and usually on a scholarly subject. In library cataloging, ''monograph'' has a broader meaning—that of a nonserial publication complete in one volume (book) or a definite number of volumes. Thus it differs from a serial or periodical publication such as a magazine, academic journal, or newspaper. In this context only, books such as novels are considered monographs.__FORCETOC__ Academia The English term "monograph" is derived from modern Latin "monographia", which has its root in Greek. In the English word, "mono-" means "single" and "-graph" means "something written". Unlike a textbook, which surveys the state of knowledge in a field, the main purpose of a monograph is to present primary research and original scholarship ascertaining reliable credibility to the required recipient.

Erik Acharius
Erik Acharius (10 October 1757 – 14 August 1819) was a Swedish botanist who pioneered the Taxonomy (biology), taxonomy of lichens and is known as the "father of lichenology." Acharius was famously the last pupil of Carl Linnaeus. Life Acharius was born in 1757 to Johan Eric Acharius and Catharina Margaretha Hagtorn in Gävle.Sernander., K. “Erik Acharius - Svenskt Biografiskt Lexikon.” Fredrik Teodor Borg - Svenskt Biografiskt Lexikon, sok.riksarkivet.se/sbl/Presentation.aspx?id=5503. He received a private education until he was admitted to Gävle Gymnasium in 1770. Later he matriculated at Uppsala University in 1773 where he studied natural history and medicine under Linnaeus and was the last student to defend a dissertation before him.Thell, A., Kärnefelt, I., Seaward, M., & Westberg, M.
